HARTFORD, S.D. – On Monday, April 14, 2025, construction work begins on Interstate 90 (exit 387) at Hartford. During the construction project, lane closures will be placed at various times on the eastbound and westbound lanes of I-90. Speed limits will be reduced to 65 mph through the work zone on I-90.

The project also includes work on Western Avenue from south of Jeffrey Street to Diamond Trail in Hartford. A two-way traffic configuration will be placed on Western Avenue. 

This project will include reconstructing the standard diamond interchange at exit 387 and replacing the structure over I-90. Western Avenue will be reconstructed as a three-lane roadway with a center left-turn lane, curb and gutter, sidewalk, and a shared use path. Additionally, the City of Hartford will have a project starting that extends the reconstruction of Western Avenue from Diamond Trail to the north of Mickelson Road. Motorists are asked to stay alert for workers, equipment, and slowed traffic through the work zone.

The prime contractor for this $12.6 million project is D & G Concrete Construction Inc. of Sioux Falls, S.D. The overall project completion date is June 2026.
